The portion of mining revenue retained by a pool for infrastructure, payout smoothing and services.
Pool fee is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Pool fee sits between protocol rules, economic incentives and software operated by independent participants. In Bitcoin, no component is authoritative by itself: miners propose history, fully validating nodes enforce validity, and users decide which rules and software they accept.
Understanding Pool fee helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
